WINDOW-SHUTTER.

Specification of Letters Patent. Application filed May 4, 1912. SerialNo. 695,312.

Patented Aug. 26,1913.

To all whom it may concern:

Be it known that I, AnoLr ELEFANT, subject of the Emperor ofAustria-Hungary,

' residing at Los Angeles, in the county of Los Angelcs and State ofCalifornia, have invented a new and useful Improvement inWindow-Shutters, of which the following is a specification.

My invention relates to improvements in window shutters, and the objectof my invention is to provide a'shutter that may be easily rolled up ordown, with open or closed slats, and which may be extended and locked ina slanting position from the window. I attain this object by means ofthe mechanism illustrated in the accompanying drawings, in which+ Figure1 is a rear elevation of the shutter closed. Fig. 2 is a cross sectionalview of Fig. 1 on the line X'X. Fig. 3 "is a broken view of one cornerof the shutter and easing showing the slats drawn apart. Fig.4 is asectional viewof Fig. 3 on line X -X Fig. 5 is a similar view to Fig. 3showing the shutter slats closed. Fig. 6 is an enlarged detail view ofthe ratchet belt wheel and the locking lever. Fig. 7 is an enlargeddetail view-of the extension arm. Fig. 8 is a side view of Fig. 7. Fig.9 is a View showing a cranking method of turning the ratchet wheel.

My shutter is composed of a plurality of slats adjustably attached tolinked bands adapted to carry the shutter to and around a roller at thetop of "the window casing. The slats 13, may be made of wood or of metaland of any desired width. They are secured to the linked bands 12, bymeans of the pins, let, on the band engaging the slots 13 in the slats.These slots allow enough play'to cause the slats toscparate and leave anopen space between theinwhen partly drawn up. The linked bands, 12, havethe upper ends secured to the roller 3, in the roller box 2, the saidroller being journaled in the bearings 5 in the casing 1 by the pins 4,On one end of the roller 3 is fixed the drum 6, on which is reeled thebelt 7. This belt runs over the roller 6 on the inside face of thecasing and down the casing to the plate 8, and through the slot 9 insaid plate to the drum 18, which is provided with the ratchet 19. Thelocking lever 20, whose wheel from back movement.

pawl 20 is adapted to engage the ratchet- 19 is designed to normallylook the ratchet By depressing this lever the ratchet is unlocked andthe belt released to run upward, and allow the shutter to slidedownward. When drawn up by pulling .down on the-belt 7, the slatsseparate leaving openings between them. -When let down the tongues 22englage the grooves 21 and close the shutter s ats.

The shutters are confined in the grooved frame 12" which fills thewindow casing movably and is hinged at 23, and the whole shutter may beextended from the hinge 23 outward and held locked in that position bymeans of the extension arm 15, which is hinged at its ends to thebottomof the shutter frame and the casing respectively, and locked by theknuckle joint 16, the crank handle 17 being used to extend and lock thearm.

As shown in Fig. 9, instead of pulling on the belt 7, I may use thecrank 29 on the crank shaft 26 in the bearings 27, and on which isformed the pinion 28 adapted to engage the gear 25 on the drum.

The shutter may be pulled entirely or partly up, or let entirely downat,will, and locked by the locking lever 20, and the looking hook .24and the slats of the shutter opened or closed by a short pull or loosening of the friction belt 7 respectively. These slats fitting together ina notched tongue and groove manner make the shutter fire proof and windproof as well as light proof. The provision for extending the bottom ofthe shutter out from the casing allows the entrance of air and lightWhile shading the window from sunlight and storms.

What I claim as my invention and desire Letters Patent for, is

In a window shutter the combination with a frame, of a plurality ofslats slidably mounted on a link band in said frame,

means for connecting said slats with said band, and means for slidablyregulating the openings between said slats.
